Abstract

The invention discloses a large-scale water turbine guide vane two-end journal synchronous-processing device and method. The device comprises a bed body, a guide vane positioning tool, a left milling head, a right milling head, a left driving tool and a right driving tool. Through one-step alignment, the device realizes synchronous-milling of two-end journals of a guide vane. The device and the method have the characteristics of strong versatility, operation simpleness, good repeatability and low production cost and satisfy processing requirements on various types of guide vane two-end journals.

Description

Technical field: [0001] The invention relates to a device and method for simultaneously processing shaft journals at both ends of a guide vane of a large water turbine. Background technique: [0002] Turbine guide vane is an important part of the water guide mechanism of the turbine, generally in the form of a middle petal body and journals at both ends. Because of the technical requirement to ensure that the façade gap is almost 0mm in the fully closed state of the water guide mechanism, its processing is relatively difficult, especially the coaxiality of the diameters at both ends is extremely high, and horizontal lathe processing is generally used. The structural characteristics of the horizontal car determine that only one end of the journal can be processed in a single processing, and then the other end of the journal is hoisted and clamped again, and because the coaxiality of the two ends of the journal is required to be high, repeated lifting and finding often occur. ...
